Berwick is lagging behind in savings
Savers in the Berwick area have an average pension pot of Â£30,608 - half the national average.
Pensions specialist Portas Financial has analysed the pension savings of its customers and created a retirement savings index.
Northumberland is just above average, with savers having an average pension pot of £68,938.
There were averages of £202,436 in Hexham, £71,276 in Morpeth and £30,608 in Berwick upon Tweed.
The average pension pot size across the whole of England is £63,387.
The top counties with the largest pension pots, on average, were all from the south east of England, with Surrey topping the poll on £87,947, followed by Herfordshire.
Bottom of the list was Avon on £34,870, followed by Worcestershire.
Jamie Smith-Thompson, Portal Financial, managing director, said: “The map gives an interesting insight into the saving habits of retirees across the country.
“Southern counties have the greatest pensioner affluence as do some of the popular seaside and countryside locations such as Dorset or Northumberland.
“However, what is clear is that many pensioners have fairly modest pension pots available to them at retirement.”
